PAMELA

PAMELA (PArallel MEsh LibrAry) is a C++ library dedicated to the mesh manipulation in parallel.

Features

Mesh reader

PAMELA provides tools to read meshes from several formats

• GMSH v2
• INRIA MEDIT Mesh
• ECLIPSE file formats (.GRDECL and .EGRID).

Mesh partitioner

PAMELA provides a basic tools to partitionate meshes. PAMELA can also use METIS to do the partitioning.

Mesh cleaner

PAMELA is able to perform several operations related to mesh cleaning. If PAMELA is compiled with MPI, these operations are done in parallel.

Mesh converter

PAMELA provides tools to write meshes to several formats:

• VTK
• Ensight Gold

Getting started

Mandatory prerequisties

• CMake
• A C++11 compiler.

Optional dependencies

PAMELA can compile as a standalone but can be used with other libraries:

• A MPI implementation (e.g. OpenMPI ).
• METIS for mesh partitioning.
• VTK for output.

In order to benefit to the full features of PAMELA, we advise the user to compile VTK with the CMake option VTK_USE_MPI set to On.

Download PAMELA

PAMELA uses git and has several submodules. To get the code, please ensure that the git lfs module is installed on your system. Instructions to get git lfs can be found here.

git clone git@github.com:GEOSX/PAMELA.git
git submodule init
git submodule update

Configure and build PAMELA

PAMELA uses CMake as a build system generator and 4 options you can choose to activate or not

ENABLE_MPI

To use PAMELA with MPI

PAMELA_WITH_EXAMPLES

To compile the PAMELA use cases

PAMELA_WITH_VTK

To use VTK for ouptut

PAMELA_WITH_METIS

To use METIS to partitionate the mesh.

For instance:

mkdir build
cd build
cmake .. -DENABLE_MPI=ON -DPAMELA_WITH_EXAMPLES=ON -DPAMELA_WITH_VTK=ON -DPAMELA_WITH_VTK=ON -DPAMELA_WITH_METIS=ON
make
